I am using Acrobat XI Pro. I just migrated to a new PC (Windows 10). I had a digital signature on my old PC (Windows 7) which may have been created in Acrobat 9 Pro - not sure. In any case, it contains our company logo, my name & title, and it time/date stamps when it is applied to a document. I find myself unable to recreate anything remotely similar. Is there a way to export this and import into the new PC? I have searched, and found someone suggesting that the appearances.acrodata file simply needed to be moved, but that was not successful. I even tried moving the old Security folder to the new machine and that did not help. Any ideas?
